Abstract
A power supply system is provided with a secondary battery, a memory unit, a calculation unit and a SOC characteristics acquiring unit. The memory unit stores initial characteristics data having a relationship between the open circuit voltage and the capacity for the secondary battery before being deteriorated. The calculation unit utilizes the initial characteristics data to calculate a deteriorated characteristics data which is a relationship between the open circuit voltage and the capacity of the deteriorated secondary battery. The SOC characteristics acquiring unit acquires the relationship between the open circuit voltage and the state of charge of the deteriorated secondary battery by dividing the capacity value included in the deteriorated characteristics data by the fully charged capacity of the deteriorated secondary battery.
